以下是一家银行的计算break up cost的公式。请问大家,这家银行的收费是否合理?
ABC calculates its break costs using the following formula:
Break cost = max[0, P* (SW_1 - SW2) * (1 - (1 + SW_2)^ (-n) ) / SW_2 ]
where:
P = Net early repayment
n = Number of scheduled repayments until the end of the fixed interest period
SW_1 = Swap rate per period for the term of the fixed loan period, as at the start of the fixed loan period.
SW_2 = Swap rate per period for the remaining term of the fixed loan period, as at the date of the early repayment
